I know this comes from time to time, but there is always something new or new experiences to share.

So, looking for some coating to use on a truck cab. I have used POR-15 and KBS in the past with good results, although seems like a lot of prep work.

What works for you guys?

I buy this at home depot. It's cheap and work great! It's located where all the thinners and paint clean up stuff is.

zero rust. 1/2 the price of por15 and it does the same thing.

I media blast all the rust away in my life. Don't care for the chemical approach myself.

Black Beauty copper slag.

I'll look into Zerorust.

Media blasting is out of the question. I am sure that is the best approach though.

Is the Home Depot stuff just an etcher?

I would be looking into rust eliminators, not rust "killers" ( or covers/encapsulators like Zerorust, POR15 etc.). Covered up rust ALWAYS returns, its only a matter of when.

I like Evaporust. It seems to Eat the rust away completely as opposed to sealing it up. As a bonus, it's not very bad on you skin if you get it on you. Supposedly you could drink it but I wouldn't try it.

Check this out (watch the video) same type of product as Evaporust concerning safe non toxic rust (only) remover. www.safestrustremover.com

I have had great results with Eastwood rust encapsulator and good old red Rustoleum. Clean very well to get any/all grease off. Wire wheel or scrape to get any loose rust or paint off and prime. Rust encapsulator can take an automotive top coat with fairly short dry time (overnight). Red Rustoleum needs lots of cure time if you want to put automotive paint over it as the solvents can lift it.

Yes and I was so impressed with it I am now a dealer for them (and just in case anyone is wondering, I only sell it locally so my post is not some sort of thinly veiled sales pitch). It does everything it says it will on the website.


I compared it directly with Evaporust (which is also a very good product). Basically it does the same thing but with a few advantages. It costs a little less than ER for two reasons, #1, it is roughly $85.00 for 5 gallons (shipping can vary that a bit) which is less than ER usually costs around here, and #2, I've found that it will last longer/processes more rusty parts before it stops working.

While both products attack only the rust causing no damage to good metal, plastic, paint markings, etc. SRR is a thinner product, nearly the consistency of water while ER is thicker, something similar to antifreeze. Because of this you can use a recirculation pump to pump the SRR over the parts (for larger parts or areas this is critical because you need to submerge parts entirely if using ER) you can pump ER over parts as well but it's thicker viscosity can overwork and burn up pump motors.

It leaves a nice clean surface on bare metal. Once I remove parts from it I don't even rinse them off, I just wipe them with a clean rag and let them dry, this keeps the parts protected from flash rust for a few days (or longer). Once I am ready to treat the parts with paint or rust protectant like ECS's RPM, I simply wipe them down with wax and grease remover and treat them as normal.

*FWIW I've used EVERY rust removal product mentioned on this thread and can honestly say that while each is a good product for it's intended use, nothing with the exception of ER comes close to SRR when it comes to the job of efficiently removing rust from parts in a safe manor (that won't etch, dissolve, or damage, good metal or other parts).

Lots of different stuff out there. The Bowers stuff looks interesting.

I am not looking to remove rust, but coat over it.

Thanks guys

I am sure that most of these products work fine for their own recommended use, but what would be the perfect product for metal a barn roof.

I usually blast any rust away and then treat the area with Permatex Rust Inhibitor. Turns the area black. Works wonderfully.
